Ask Erina anything. Get a cited answer.

How it works

• Tool-use, not memorization. Erina has a catalog of tools — get_radar_multi_hit, get_ticker_snapshot, get_trade_ideas, get_options_flow, and dozens more. It picks which to call based on your question.
• Grounded in live data. When you ask "what changed for AMD this week," Erina pulls this week's news, options flow, price action, and revisions — not something from training data.
• Cited answers. Every claim is backed by a tool call you can inspect. Cost is metered per-call so you can see exactly what the answer cost.
• Conversation history. All your prior chats are saved and searchable. Export any conversation as a PDF.
• Deep links to the app. When Erina recommends a trade or references a ticker, those chips are clickable — jump straight to the ticker page, Trade Builder, or Radar list.

Examples of what people ask

• "Give me a covered call idea for NVDA that yields at least 2% and gives me 10% downside protection."
• "Which semis are on more than three Radar lists today?"
• "What's the earnings history look like for CRWD — beat rate, average post-earnings move, IV crush?"
• "Are dealers short or long gamma on SPX right now?"
• "Show me my portfolio's beta-weighted delta and how much SPY I'd need to hedge."
